Answer:
The two types of clauses are:
1. **Dependent/Subordinate Clauses:** These are clauses that cannot stand alone as complete sentences and rely on an independent clause to form a complete thought. They often begin with subordinating conjunctions like "because," "although," "if," "when," etc.
2. **Independent Clauses:** These are complete sentences that can stand alone and convey a complete thought. They do not rely on other clauses to make sense.
